Definitions

  • the present invention relates to a vehicle tyre loading-unloading device.
  • the present invention relates to a vehicle tyre loading-unloading device for a tyre processing unit, the device being substantially of the type disclosed in FR-A-2370574 and comprising a mobile tyre-handling unit in turn comprising a lower unit having gripping means for releasably suspending a first tyre, and activating means for moving said mobile tyre-handling unit in relation to said tyre-processing unit.
  • the device of the present invention may be employed to advantage for loading/unloading tyres on/off a curing unit comprising an upper half mold, a lower half mold and a device for parting the two half molds at the end of each curing cycle; and wherein the two half molds are so formed that, when parted, the cured tyre remains integral with the upper half mold.
  • a vehicle tyre loading-unloading device for a tyre processing unit, the device comprising a mobile tyre-handling unit in turn comprising a lower unit having gripping means for releasably suspend a first tyre, and activating means for moving said mobile tyre-handling unit in relation to said tyre-processing unit; the device being characterized in that said mobile tyre-handling unit further comprises an upper unit having plate means for supporting a second tyre; and by further comprising fixed supporting mean for said mobile tyre-handling unit; said activating means being designed to move said mobile tyre-handling unit through the processing unit and between a loading station, wherein said first tyre is gripped by said gripping means, and an unloading station, wherein said second tyre is unloaded.
  • Number 1 in Fig.1 indicates a tyre curing system comprising a conveyor 2 for successively feeding green tyres 3 to a loading station 4; a curing unit 5 for receiving tyres 3 and producing cured tyres 6; a conveyor 7 for transferring tyres 6 from an unloading station 8; and a device 9 for transferring both tyres 3 from loading station 4 to curing unit 5, and tyres 6 from curing unit 5 to unloading station 8.
  • Curing unit 5 is of known type as described, for example, in US Patent n.4,747,765, the content of which is fully incorporated herein.
  • Unit 5 comprises a lower portion 10 and an upper portion 11 designed to move in relation to each other, by virtue of hydraulic lifting devices 12, between a closed curing position (not shown) and an open position (Fig.1) for unloading tire 6 and loading tire 3.
  • Device 9 comprises two guide columns 13 extending upwards from a fixed base 14 and connected by an upper crosspiece 15 designed to move parallel to a vertical axis 16 in relation to base 14 by virtue of a hydraulic actuator 17.
  • Crosspiece 15 is connected to a coupling 18 coaxial with axis 16 and connected to an actuator 19 so as to turn in relation to crosspiece 15 about axis 16.
  • Device 9 also comprises a mobile loading and unloading unit 23 connected integral with the free end of portion 22 of arm 20.
  • unit 23 comprises an upper unit 24 for supporting tire 6, and a lower unit 25 for suspending tire 3 coaxially with tire 6.
  • Unit 24 comprises a cylindrical body 26 integral with the free end of portion 22 of arm 20 and having a vertical axis 27.
  • the top end of body 26 is fitted with a plate 28 defined externally by an upward-tapering, substantially truncated-cone surface 29 coaxial with axis 27.
  • the bottom end of plate 28 presents an outer flange 30 defining a support for the bead portion 31 of tire 6.
  • Unit 25 is connected integral with the bottom end of body 26, and comprises a known device 32 for gripping tire 3.
  • Device 32 comprises, in known manner, a central actuator 33 integral with the bottom end of body 26 and having a number of output rods 34 moving substantially radially between a withdrawn position (not shown) and an expanded position (as shown in Fig.2).
  • Each rod 34 is fitted on its free end with a pin 35 parallel to axis 27 and fitted on its bottom end with a substantially T-shaped bracket 36 designed to support and grip the bead portion of tire 3 and suspend tire 3 beneath body 26.
  • actuator 19 is operated for positioning unit 23 over tire 3 in loading station 4; and actuator 17 is operated for lowering unit 23, gripping tire 3 via gripping device 32, and raising unit 23 with tire 3 suspended on unit 25.
  • Actuator 19 is then operated once more for moving arm 20 towards curing unit 5 and positioning unit 23 between upper and lower portions 11 and 10 already opened by hydraulic devices 12.
  • unit 23 is coaxial with portions 10 and 11 of curing unit 5, gripping device 32 is operated so as to withdraw rods 34 and drop tire 3 inside lower half mold 37 on lower portion 10 of unit 5. Unit 23 is then withdrawn from unit 5, which is closed for curing tire 3 and producing cured tire 6.
  • unit 23 is moved into station 4 for picking up another tire 3 and transferring it to unit 5.
  • portions 10 and 11 are parted by devices 12, which results, in known manner, in tire 6 being detached from lower portion 10 and remaining attached to upper portion 11.
  • Unit 23 is then inserted once more between portions 10 and 11, so that unit 24 is located beneath tire 6 attached to portion 11, and unit 25, to which the next tire 3 is suspended, is located over lower half mold 37.
  • tire 6 is detached from portion 11 by a known extracting device 38 and dropped on to plate 28 with its bead portion 31 substantially resting on flange 30, and the next tire 3 is dropped on to half mold 37 by withdrawing rods 34 on device 32.
  • unit 23 is then withdrawn from curing unit 5; moved over to unloading station 8; turned over, by rotating portion 22 of arm 20, so as to unload tire 6 on to conveyor 7; restored to the normal position with unit 24 upwards; and, finally, returned to loading station 4 to pick up the next tire 3 via device 32 and await the next unit 5 unloading-loading cycle.
  • a vertical guide 40 having the same function as columns 13 in Fig.1 is connected to an apron 39 fitted to lower portion 10 of unit 5 for connecting lifting devices 12.
  • Guide 40 is defined, at its opposite ends, by two transverse plates 41 between which is mounted for rotation a screw 42 which, together with its drive motor 43, constitutes an actuator, similar to 17 in Fig.1, for moving along guide 40 a slide 44 similar to crosspiece 15 and connected in sliding manner to guide 40.
  • Slide 44 is connected integral with a fork 45 supporting a rotary pin 46 extending along an axis 47 corresponding with axis 26 in Fig.1, and powered (in a manner not shown) so as to turn about axis 47.
  • Pin 46 is connected integral with the outer casing of an angular actuator 48 constituting a first portion of arm 20, the second portion 22 of which is connected to loading-unloading unit 23, extends along axis 21, and is designed to turn about axis 21 by virtue of actuator 48.
